HEADLIGHT.

To all whom it may concern:

Be it known that I, FRANK P. AHMAN, a citizen of the United States, residin at Norfolk, in the county of Norfolk and tate of Virginia, have invented certain new and useful Im rovements in Headlights, of which the ollowing isa specification, reference being had to the accompanying draw- Bhis invention relates to certain improvementsin headlights and has relation more particularly to a device of this general character especially designed and ada ted for use in connection with an automo ile, and it is an object of the invention tb provide a novel and improved deviceof this eneral character including a deflector w ich i with novel and improved means -whereby the same are maintained in installed or assembled relation.

Another object of the invention is to provide a device of this general character including novel and im roved means whereby the lens may be hel in working position and readily applied or removed.

Ithe invention consists in the details of construction and in the combination and arrangement .of the several parts o f my improved headlight whereby certain impertant advantages are attained and -tlie device rendered simpler, less ex ensive and otherwise more convenient an `advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that m invention may be the better understoodz will now proceed to describe the same with reference to the accompanying drawings, wherein v n Fi ure 1 is aA vertical sectional view taken longitudinally through a headlight con- Specicatlon of Letters ateiit. Application tiled May 28, 1919. Serial No. 30,350.

Patented Apr. 13, 1920.

structed in accordance with an embodiment of my invention.

Fig. 2 is a view in front elevation of the deflector as herein comprised.

Fi 3 is an enlarged fra mentary sectiona view taken lon tudinal y of the headlight as herein enibo ied and at the lforward end -thereof. i

Fig. -l is a sectional view taken substantially on the line 4 4 of Fig. 3.

Fig. 5 is a view in front elevation of the structure illustrated in Fig. 4., and

Fig. 6 is a fragmentary view,l partly in section and partly in elevation, illustratmgl a portion of the means for maintaining theglens in ap lied osition.

Pts disclose in t e accompanying drawing C denotes the casing o my im roved hea light which is of a conventiona style an w iichhas its open or light emitting end defined byan inwardly directed continuous fla ,r e 1. Secured to the flan 1 is a lural y of equidistantl s ace outstan ing hook members 2, pre 'era ly three in number. and which hooks are adapted to coact with inwardly directed fingers 3 or the like carried by the supporting anniilus or ring` A for the lens L.

R denotes a reflector insertible within the casing C through the open or light `eiiiitting end thereof and the forward end portion of said reflector is defined by the outstanding continuons flange el which, when the reflector R is in applied osition, overlies the flange l of the casing The flange 4 is provided with the circiimferentially directed slots 5 through which the hooks 2 are directed and whereby said hooks serve as supports for the reflector 'RL The inner end portion of the reflector R carries an illuminating member M of any desired type but preferably electrical.

D denotes a tyleflector in its entirety and which is arranged within the forward end Portion of the reflector R inwardly of the ens L when the headlight is installed or assembled. The deflector D. comprises a frame 6 partially extending within the forward or open end of the reflector R and the forward marginal portion thereof is de-v fined by a continuous outstanding flange 7. The flange 7 is also provided with the cirioo whereb ,said hook members 2 also serve to maintainfthe deflector in'installed or assembled position.-

Intersecting thc frame 6 and' suitabl cured thereto are the substantially ori zr' ally disposed slats or ilat stri s 9 of e wid-ih substantially equal to the eiigth of the frame 6 and referbly nidistantly spaced in a vertice direction. he slats or flat stri s 9 are inclined 4downwardl and {orwarc y in cross section and the e ree of inclination is such 'that the forwar .or lower marginal pgrtion of each of theslatei4 or strips 9 is low the upper or inner mar 'nal portion of the slat or strip 9 iinine diategl'ly thercbelow. By this arrangement of the slats or stri s 9 is prevented direct view of any brilliant y illuminated portion of the headlight by an observer having the line of by the rellector L -may be effectively vision higher than the level at the top of the headlight but permits an effective illumination of the roadway.

Each oi the hook members 2 is also directed through the central portion of an outbowed spring 10 which, when the head-v light is installed or assembled, is interposed between the flanoes 1 and 4 and serves to constantly urge tie reflector R and the deilector D outwardly, and whereby the flanges 4 and 7 are maintained in contact and the flange 7 in contact with the fingers 3, .wlieic- R and dellcctor D are main: tained in desired relation and against undue .vibration The annulus or ring A has its outer marginal portion defined by the inwardly directed flange 11 and secured to the innerfaees of the annulns or ringr A and the flange 11 is a stilening ring 1:2. The fingers 3 hereiiibefore ieferred to aie directly carried by this ring 12. l

The ring 1'2 is substantially L-sliaped in cross section and the free iiiarfvinal portion overlying the flniigell is provi( ed with the inwardly offset and eqnidistantly spaced wings 14 beneath which is adapted to be engaged the outer marginal portion bf a lens engaging ring 15. T he einer marginal pori tion of the ringr 1:3 is provided with the notches 1G to permit the proper engagement of the ring 15 beneath the wings l-l upon a partial rotation ol said ring 15. Wien the ring 15 has been partially rotated to effect t'iis engagenient` each of the wings 14 engages between a pair of outstanding protiiberances` 17 ireferably pressed ont. of the ring 15, and w iereby the ring 15 is lielil against rotation and thereby maintained in working position.

The ring l5 has its inner margin arranged inwardly of the inner margin of the Bange 11 so that the marginal portion oftlie lens held between the flange 11 and the 1ring 15. In order that the ring `15 may plroperly en age the margnal portion of t e ens L, t e inner marginal portion of said ring 15 is offset, as indicated at 18.

The slots 5 and 8 are of a. length to riiiit the ready insertion or withdrawn of the hook members 2 therethrough and when the reflector. R and the dellector D are rotated in one direction, the outer end ortion' of the hook members 2 coact with t4 e portions ofthe (langes 4i and 7 immediately adacent they slots 5 and 8. y

o remove the dellector and the reflector R, the same are 4rotated in the opposite direction to the extent alici-ded by the slots 'Eiland-8 and when i'n this latter position 'said deflector D and reflector R ma be readily removed, it being understood o course that the anniilus or ring A hasbee'n previously removed. It Vwill also be understood that when the delector vD and the reflector R have been removed, the springs 10 are retained by the hook members 2. y

From the foregointghndeso'rpton it is thoughtkto beobvious t a headlight constructed' iniiocordaiice is Particularly'n well4 ada o the convenience an I it ma.' be assembled 4and operated, and it will also be obvious that my nventonis susceptible of some change and modifica# tion without departing fromV the principles and spirit thereof and for this reason I do not wishjto be understood as limitin myted for use b .reason `tion o'f the several parts herein shown in carrying out my invention in practice ex.

cept as hereinafter claimed;

I claim: l
